Speciication of Letters Patent No. 33,074, dated August 20, 1861.

To all whom it may concern:

rcuse, in thecounty of Onondaga and State of New York, have invented anew and Improved Machine for Making Spokes for lVheels; and I do herebydeclare that t-he following is a full, clear, and exact description ofthe same, reference being had to the annexed drawings, making a part ofthis specification, in which- Figure l is a side sectional View of myinvention taken in the line Fig. 2. Fig. 2 is a plan or top sectionalview of my invention, taken in the line y, y, Fig. l. Fig. 3 is atransverse section of my invention taken in the line a, a, Fig. l. Fig.4 is a transverse section of my invention taken in the line a', a', Fig.l. Fig. 5 is a transverse section of my invention, taken in the lineai', Fig. 1. Fig. 6 is a transverse section taken in the line y', y,Fig. l.

Similar letters of reference indicate corresponding parts in the severalfigures.

The object of this invention is to obtain a machine whereby spokes maybe made with great rapidity and in a perfect manner.

The invention consists in the employment or use of a series of carriagesplaced in an inclined bed and used in connection with suitable rotarycutters and pressure rollers; all arranged as hereinafter shown anddescribed to eect the desired result.

To enable those skilled in the art to fully understand and construct myinvention I will proceed to describe it.

A represents an inclined bed or frame which is properly supported by aframing or legs a; and B represents a series of car- `riages which areplaced 1n the bed or frame A, and work on guides 5,6', said guides beingplaced in pairs one over the other, the

` upper guides being for the working or feedmg movement of the carriagesand the lower guides for the return movement of the same.

On the bed or frame A, there are firmly secured cross-heads C, C', D, D.In the cross-headsI C, D, Athere are fitted vertical slides E, two ineach; and in the lower end of each slide E, there is fitted a roller F.Each slide E, has a weight G, attached to its upper end.

In each cross-head there is placed a horizontal lever H, having apendent pin or rod I, attached. Each rod I, has a roller J on its lowerend, and to each lever I-I, there is secured a cord K, having a weightL,

attached.

In the cross-heads C', D, there are placed vert-ical slides M', two ineach. These slides have each a weight N, secured to them and the lowerends of the slides of each crosshead have bearings O, attached, in whichthe joints of a roller Q, are fitted loosely.

Between each pair of cross-heads C, C', I), D, there are placed rotatingshafts R, on which cutters S, are secured. The cutters S, that arebetween the cross-heads C, C', are for planing off the edges of thespokes while those on the shafts between the cross-heads D, D, haveconcave cutting edges and plane the sides of the spokes-see Fig. 2, inwhich the forms of the cutters are shown.

The journals of the cutter shafts R, are fitted in sliding or adjustablebearings T, which may be arranged in any suitable way and said shaftsmay be rotatedor driven by any convenient power. In the lowermostcross-head C, there is placed a shaft U,which has a pinion V, on it,said pinion gearing in racks ai, on the carriages. Each carriage B, hasa central guide or bearing strip bi, upon it.

In the lower part of the inclined bed or frame A, at each side, there isfitted a horizontal slide I-I. These slides are `allowed to work freelyin the bed or frame and each has a spring I, bearing against its outeredge,

said springs having a tendency to keep the slides H, shoved inward. Theinner edges of the slides H, are beveled to admit of the carriages B,shoving them outward, as they reach the termination of their downwardmovement on the lower guides o.

j The operation is as follows: The stuff from which the spokes are cut,is placed on the carriages B, two on each carriage, and the lattershoved upward by the attendant, so that the pinion V, may engage withthe rack ai?. The rollers F, Q, J, keep the stuff down in properposition on the carriages, while the rollers J, keep the stuff bearingrespectively against the strips 6*, and the inner sides of the racks Thefirst cutters S, between the cross-heads C, C', plane oftl and finishthe edges of the spokes, while the second cutters, between thecross-heads D, D', plane olf and finish the sides of the spokes, that isto say, the upper side of them in convex form. As each carriage B,reaches the top of the bed or frame A, it drops down on the lower guidesbf, and descends by its gravity to the bottom of the bed or frame, andforcing outward the slides H, passes upward on the upper guides b. Theoperator vthen turns the stuitq on the carriages which are shoved upwardas before and the opposite sides of the stuff are finished. The slidesH, it will be seen adinit of the carriages being shoved directly upwardon the guides Z), to the cutters. It being understood that one carriageB, shoves up the other above the pinion V, the latter, of course, onlyactin@ on one carriage at once.

Having thus described iny invention what I claim as new, and desire tosecure by Letters Patent, is

1. The series of carriages B, placed in an inclined bed or frame A, 1nconnection wlth the vertical and lateral pressure rollers F, Q,

J, vertical slides E, weights G, horizontal 20 bars H, rods I, verticalslides M, weights N, and rotary cutters S, arranged for joint operationas and for the purpose herein set forth.

f2. The slides H', when arranged and used 25 1n connection with theparts above enumer-
